Fiona was a continuation of Gertie which crossed the east coast and Peninsula and entered the SE Gulf. A tidal wave was seen to come up from the mouth of the Nassua River and split at Cattle Creek. The wave came over the flats and washed away 3m high walls. It was 4.6 m high and travelled inland for approximately 2 km. At Edward River Mission the sea washed out a road on one of the sand ridges 2.7 m above sea level. At Aurukun a tidal surge of 0.9 m was observed in the river about 5 miles from the Gulf.
